Preventing HIV: How to Use Pills to Prevent HIV

To cut the HIV risk by as much as 92%, there are several catches. For example:

  • The AIDS drug Truvada must be taken every day, not just prior to sex.
  • Truvada, like all HIV drugs, has side effects.
  • Truvada is expensive. Since PrEP is not an FDA-approved use of the drug, insurance may not cover the cost.
  • PrEP does not prevent other dangerous sexually transmitted diseases.
  • Drug-resistant HIV virus develops in men who begin PrEP when already infected with HIV.

U.S. public health agencies are developing PrEP guidelines. But since the news is out -- and men already are asking their doctors whether PrEP is right for them -- the CDC today issued preliminary guidelines.

Preliminary PrEP Guidelines

  • Since PrEP was tested only in men (and male-to-female transgendered women), PrEP should be given only to biological males.
  • PrEP should be offered only to HIV-negative men at high risk of HIV infection; that is, they should frequently change sexual partners or have concurrent partners in a region with high HIV prevalence.
  • PrEP should be just one part of a comprehensive prevention plan.
  • PrEP must include regular HIV testing.
  • Providers offering PrEP must regularly monitor patient adherence, drug side effects, and HIV risk behaviors.
  • The only PrEP drug regimen tested is once-daily Truvada; other anti-HIV drugs should not be substituted.

Before starting PrEP:

  • Test for HIV, including a sensitive test for recent infection if there are any symptoms of acute HIV infection.
  • Test for hepatitis B infection.
  • Test for sexually transmitted diseases.
  • Check for normal kidney function.

When starting PrEP:

  • Take one Truvada tablet every day.
  • Providers should offer counseling on reducing HIV risk behavior and on Truvada adherence.
  • Providers should offer condoms.
  • Providers should prescribe no more than a 90-day supply, renewable only when HIV testing is negative.

During PrEP:

  • Test regularly for sexually transmitted diseases.
  • HIV testing should be done every 60 to 90 days.
  • Health providers should perform regular lab tests to evaluate Truvada side effects.

When PrEP is discontinued:

  • Test for HIV. If HIV test is positive, evaluate whether virus is drug-resistant. If HIV test is negative, men should be referred to appropriate HIV prevention services.

The CDC's full preliminary PrEP guidelines appear in the Jan. 28 issue of Morbidity and Mortality Weekly Report.
